Nitin Saksena, Head of US Equity Derivative Research, BofA Securities

There's always a bull market somewhere, and in today's climate of hyper short termism, both volume and commentary are thriving in the land of zero days to expiry options. While the risk characteristics of ODTEs are generally agreed on, the directionality of the flows and resulting positioning remain subjects of vigorous debate. With this in mind, it was a pleasure to welcome Nitin Saksena, the Head of US Equity Derivatives Research at BofA Securities, to the Alpha Exchange. Before embarking on the work that Nitin and team are doing to better understand these ultra short dated options, we survey the landscape of cross-asset vol. Here, Nitin notes that options on certain currency pairs - for example in the Canadian dollar - score on the cheap side on a nominal basis. On a relative basis, rate vol remains substantially high compared to SPX vol as the MOVE index is just 20% off its Covid high while the VIX has declined by 80%. Next, we turn to the risk implications of the substantial flows in daily SPX options. Given the convexity, there are scenarios imagined by some in the industry in which an unwind of wrong-way exposure can accelerate price movements in the index. While respecting the logic of the analysis, Nitin pushes back on the degree to which the flows are one-way, seeing a balance of trades on the long and short side of options. Still, he cautions that because these instruments and the resulting risk exposures are new, we should be carefully monitoring them.  I hope you enjoy this episode of the Alpha Exchange, my conversation with Nitin Saksena.
